• Cast Steel Construction: Heavy-duty WCB body built to withstand harsh high-pressure, elevated-temperature environments.

• Positive Shut-Off: Precision-machined disc and seat ensure dependable, leak-tight isolation for critical applications.

• OS&Y Design: Outside Screw & Yoke configuration keeps stem threads isolated from process fluids to minimize wear and line contamination.

• Streamlined Flow Path: Hydrodynamically designed internal body minimizes turbulence and flow resistance across the seat.

• Bolted Bonnet Security: Rugged bonnet connection provides high structural integrity and enables quick inline disassembly for servicing.

• Flexible Actuation: Standard manual handwheel with options for gear operator or automated actuation on larger sizes.

• ANSI Flanged Ends: Standardized flanged connections simplify alignment, installation, and routine maintenance in existing piping runs.
